TAPER ROLLER BEARTNG.

Application filed July 31,'

To all wtomz't may concern.'

Be it known that I, ELMER E. NEAL, a c1t1- zen of theUnited States, anda'resident of Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements in TaperRoller Bearings, of which the following is a speciiication.

The principal objects of the present invention are, first, to effect aneconomy in cost and ease of production, and to provide a light andresilient roller-cage which will operate smoothly and noiselessly; andsecond, to provide a cage especially adapted to space the rollers inrespect to each other and retain them on the inner cone race of a taperroller bearing in which, means, other than the cage, are provided forkeeping the axes of the conical rollers in convergence towards acommonorigin.

In my pending application serially numbered 172,405 l have described ataper roller bearing in which the cage is not relied upon for keepingthe axes of the conical rollers convergent toward a common origin, andlsincethe present invention relates particu` larly to that type of taperroller bearing, it will be illustrated and described in connection withthe subject-matter of that application.

faces 9 provided with'openings 10, the walls of which envelop therollers at a point between their axes and their line of contact with theouter cone race. This sheet metal band is provided with an outwardflange at its larger end and with an inward flange at its smaller end.The function of the sheet metal band 8, is to include the rollers uponthe inner race and to space successive or adjacent rollers from contactwith each other. Since the constraint upon the rollers Ito make themmove in their correct path is supplied by the interaction of the flatends or the rollers and the conical shape ,of the shoulder 3, the cageis very light and resilient and therefore it operates smoothly andnoiselessly. The roller openings 10, permit the rollers to emergeoutwardly from the cage for the purpose of bearing contact with theouter race, but they are too narrow to permit of any great amount ofradially outward` displacement of the rollers, which are thus snuglyconfined upon the inner race or cone forming together with it, and alsothe cage, a self-contained unit.

From the foreging description it Yis evia dent that the cage and theother elements of the bearing -co-act in the production of the result,for the latter con-strain the rollers in their properpath and theformer, re-

lieved of that function, simply spaces the rollers and attaches them tothe inner, race.

What I claim is:

1. A spacer and retainer for taper roller bearings comprising a lightand resilient sheet metal yband having lsmooth unobstructed conicallinside and outside surfaces provided with roller openings which embracetherollers at a point between their axes and their line of contact withthe outer raceway and the edges of said openings making contactthroughout their length with the sides and ends of the rollers, andhaving an outward Hange at its larger end and an in- -ward flange at itssmaller end, the said flanges being constructed andv arranged toyreinforce said' band-fandresist radial stresses and prevent defprmationthereof, substantiallyas described.`

2. Tn a roller bearing, an inner race member having an undercut shoulderat one side of the raceway, r'oll'er members having a quadrilateralformation inv longitudinal section, and a cage member havingquadrilateral openings the edges of which fit the contained rollermembers throughout the combined length of the edges of the individualopenings, the said edges being maintained in contact with the peripheryof thecontained roller and the respective ends thereof.

3. In a roller bearing7 an inner race mem-V ber having an undercutguiding shoulder at one side of the raeeway,y taper roller meinbershaving the entire areas of their ends formed in planes substantiallyperpendicular to the axes of the members whereby said members have aquadrilateral formation in longitudinal section, and a cage memberhaving quadrilatei'al openings smaller than the maximum section of therollers and the edges of which tthe contained rollermember 4throughoutthe combined length of the edges ELMER E.
